Title: Improvements in or relating to gas holders
IPC: F17B1/007
Filed: 1952-02-12
Abstract: 712,858. Gas holders. WHESSOE, Ltd., and PARKER, G. S. Feb. 12, 1953 [Feb. 12, 1952], No. 3689/52. Class 54 Means for conveying heating fluid to a lift 6 of a spirally guided gas holder from the adjacent outer member 4 of the holder comprises a flexible hose 1 secured at its ends to the lift and to the outer member, a trough or other receiver 24 for accommodating the excess length of hose when the lift is not fully raised, and guide means 11 to travel along the receiver as the lift moves to feed the hose progressively into or out of the receiver. The hose receives steam from a lagged pipe 2 and supplies it to a lagged pipe 3 fitted with valves and ejectors for supplying the steam to the sealing liquid in the cup of the lift 7. The hose is attached by clips 9 to a pair of flexible wire ropes 8 tensioned by a weighted lever 14 and passed around the guide means 11 which is in the form of a pulley rotatably mounted on a carriage 12 and fitted with a guard 21. Three rollers 22 on the carriage engage a guide rail 23 attached to the receiver 24 while three further rollers 25 engage guide rails 26 provided on the lift 6 clear of the gauge sheeting. The lift 6 is guided at an angle of 45 degrees so that the horizontal movement of the pulley 11 is always equal to the vertical movement of the lift and the total length of the path of the wire ropes remains constant. The provision of three rollers 25 ensures that a gap 27 in the rails 26, to clear the spiral guide rails and roller brackets of the lift, is positively bridged. The receiver 24 has a slight fall to remove steam condensate. The hose may be of rubber with or without metal armouring.

Filed: 1972-01-26
Abstract: 1375093 Valves TOKYO KEIKI KK 26 Jan 1972 [26 Jan 1971] 3745/72 Heading F2V In a valve having a closure member which is accelerated to an open position and decelerated to a closed position, the closure member is defined by extension 5, 5a of a piston 3 controlled by a pilot valve 14, the extension co-operating with groove 15 to control flow to sump 18 from passage 20. With valve 14 in the position shown, fluid admitted from 19 past check valve 21 to chamber 4 maintains the piston rightwards to close groove 15. When valve 14 is moved to its alternative position, fluid from inlet 19 flows via 14e, 14g to chamber 7 and fluid from chamber 4 flows via 14h, 14f to passage 20, check valve 21 opening only after a predetermined pressure drop in chamber 4 so that piston 3 starts to shift leftwards thereby progressively opening groove 15 to allow greater discharge from chamber 4 and consequent acceleration of the piston. Return of valve 14 to the position shown allows pressure to build up in chamber 4 and the piston shifts rightwards, fluid being displaced from chamber 7 via check valve 22 and groove 15 which is progressively closed to decelerate the piston. A needle valve may be provided to by-pass the control effect at 5, 15. In a simplified embodiment (Fig. 1), the piston is spring-biased leftwards and chamber 4 is supplied through a check valve 11 bypassed by a restrictor 12, check valve 22 being omitted.

Title: Hydraulic variable speed gear
IPC: F16D67/00
Filed: 1947-02-13
Abstract: 637,516. Hydraulic transmission of power. LAZAGA, F. F. Feb. 13, 1947, No. 4205. [Class 69 (ii)] [Also in Group XXIV] A stepped-planet bevel-train yields two reduced and one direct ratios, automatically controlled by a two-element fluid-coupling 28, a centrifugal friction-clutch 80, and a friction disc-clutch 60 engagedby axial movement of one member 37 of the fluidcoupling caused by the pressure of the fluid in the coupling. A one-way detent 67 takes torque-reaction in reduced ratios and a one-way clutch 57 overruns in second speed. A band-brake 74 on the planetcarrier provides a fixed reduced ratio and, in conjunction with synchromeshed positive clutches 46, 48, reverse. The bevel planets are carried in a rotatable drum 1, and their smaller steps constantly mesh freely-mounted bevels 15, 19 selectively clutched to the axiallyslidable output shaft 12, through the clutches 46, 48 (not described) for forward or reverse respectively. The larger planet-steps engage respectively a bevel 5, fast on the input shaft 2, and a bevel 17, fast to one element 28 of the fluid-coupling, the other element 37 of which is prevented from reverse rotation by the one-way detent 67 and is also connected to the planet-carrier 1 through two parallel paths ; one including the disc-clutch 60 and one-way clutch 57 in series ; the other the centrifugal friction-clutch 80, the engaging elements of which are carried by the planetcarrier 1. With the forward positive clutch 46 engaged, as shown, and the output shaft 12 initially stationary, rotation of the input shaft 2 drives the element 28 of the fluid-coupling reversely, which is resisted by the other coupling-element 37 reacting on the one-way detent 67. Pressure then builds up in the fluid-coupling thrusting the coupling-element 37 axially to the left, engaging the disc-clutch 60 and thus, through the one-way clutch 57, applying a brake-torque to the reverselyrotating planet-carrier 1, whereby forwarddrive of the output-shaft 12 in the lowest ratio is initiated, the planet-carrier 1 being eventually brought-to rest. Increased speed and/or reduced load causes the fluid to brake the coupling-element 28 to rest, thus holding the bevel 17 and causing the planet-carrier 1 to rotate forwards in the second-speed phase, with overrun in the one-way clutch 57. At a predetermined speed of the planet-carrier 1, the centrifugal friction-clutch 80 engages, driving the fluid-coupling element 37 forwards, with overrun at the one-way detent 67 and applying a forward drive-torque through the fluid-coupling, to the bevel 17, which eventually produces a one-to-one fluid drive. Applying the band-brake 74 to the planet-carrier 1 gives a fixed-ratio forward reduction, with the positive clutch 46 engaged, or reverse with the positive clutch 48 engaged by axially sliding the output shaft 12.

Title: Improvements in or relating to cleaning the interiors of enclosed spaces by volatilegrease solvents
IPC: B60S3/00
Filed: 1936-02-14
Abstract: The interior surfaces of tanks, condensers and similar enclosed spaces are cleaned with volatile solvents, by introducing the solvent into the space in both vapour and liquid form, and subsequently removing the liquid solvent containing the impurities.  A fuel-tank car 4 containing bituminous and tarry deposits is first treated with steam to loosen the deposit to some extent to permit, removal through an outlet.  Solvent vapours are then admitted through a line 15 having discharge nozzles 16, from a vaporizer 14 connected to a tank of <PICT:0470419/III/1> trichlorethylene 9.  The condensed solvent and impurities are pumped into a sump 24 and after removal of supernatant water are pumped through a line 29 to jets 60, 61 in the tank car which may be tilted if desired.  Air containing some vapour which is initially displaced from the tank car passes through a condenser 20 to the atmosphere.  The jets of liquid solvent and solvent vapour may be supplied simultaneously or alternately after which a final vapour rinse is effected.  A proportion of the used solvent passes from the sump 24 into a still 51 from which solvent vapours may be returned to the tank car during the cleaning operation or pass to a condenser 20 to recover the solvent which returns to the storage tank 9.  Any liquid solvent in tank car is removed by tilting and draining.  Solvent vapours contained in the warm tank car, are forced into the condenser 20 by a blower 46 from which air is forced through a heater 14 and pipe 15.  During this stage the car may be heated internally or externally.  Final traces of solvent may be removed by steam.  After passing through the condenser the heated air may be treated with an adsorbent such as silica, silica gel or alumina gel.  In a modification, two stills and condensers are employed, whereby solvent recovery proceeds simultaneously with the generation of solvent vapours, and a gas holder to contain the initially displaced air is provided. Trichlorethylene may be replaced by carbon tetrachloride, ethylene dichloride, perchlorethylene, or b -trichlorethane. Specification 315,930, [Class 91], is referred to.
